[0037] In order to more comprehensively understand the features and technical content of the embodiments of the present disclosure, the implementation of the embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference and illustration only and are not intended to limit the embodiments of the present disclosure. In the following technical description, for the sake of explanation, numerous details are provided to give a full understanding of the disclosed embodiments. However, one or more embodiments can still be implemented without these details. In other cases, well-known structures and devices may be shown in a simplified manner to simplify the drawings.

[0038] In the specification and claims of the embodiments of the present disclosure and the above-mentioned drawings, terms such as "first" and "second" are used to distinguish similar objects and do not necessarily describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so as to implement the embodiments of the present disclosure described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion.

[0039] Unless otherwise specified, the term "plurality" means two or more.

[0040] In the embodiments of the present disclosure, the character " / " represents an "or" relationship between the front and rear objects, or represents a division sign. For example, A / B means: A or B, or means A divided by B.

[0041] The term "and / or" is a description of the association relationship of an object, indicating that three relationships can exist. For example, A and / or B means: A or B, or, these three relationships of A and B.

[0042] The term "correspond to" can refer to an association relationship or a binding relationship. A corresponding to B means that there is an association relationship or a binding relationship between A and B.

[0043] In the embodiments of the present disclosure, the working principle of thermoelectric refrigeration (also known as thermoelectric cooling) is based on the Peltier effect. The thermoelectric semiconductor material (also known as thermoelectric material 10) is made into a thermoelectric refrigeration chip (thermoelectric cooler, TEC), that is, a thermoelectric cooling sheet. When direct current passes through the thermoelectric material 10 and the electrodes, heat is absorbed at one end electrode and heat is released at the other end electrode. Its working effect is like transporting heat from one end to the other end, similar to a heat pump. To achieve heating of one end substrate of the thermoelectric material 10 as the hot-end substrate 20. The other end substrate of the thermoelectric material is cooled as the cold-end substrate 30.

[0044] Combined with Figure 1As shown, traditional semiconductor refrigeration components are all TEC bare devices, that is, the semiconductor refrigeration component only includes a semiconductor refrigeration chip. The semiconductor refrigeration chip includes thermoelectric materials 10, a cold-end substrate 30, and a hot-end substrate 20. The size of the semiconductor refrigeration chip is basically fixed, especially the thickness, which is often about 4 mm. For general equipment that uses semiconductor refrigeration components for refrigeration (such as refrigerators and wine cabinets, etc.), the equipment needs to be insulated, and the thickness of the insulation layer 50 is much greater than the thickness of the semiconductor refrigeration component. This makes the overall thickness of the entire semiconductor refrigeration chip the same as the thickness of the insulation layer 50. However, this requires adding components and combining Figure 2 and Figure 3 As shown, aluminum plates 40 with high thermal conductivity are usually used to make the overall thickness of the semiconductor refrigeration component reach the thickness of the insulation layer 50, which is convenient for installation. And it can enhance the assembly strength of the semiconductor refrigeration component and reduce the damage problem of the semiconductor refrigeration component.

[0045] After studying the operation of the semiconductor refrigeration component, it is found that since the refrigeration capacity of semiconductor particles is related to the magnitude of the current flowing through the semiconductor particles, and the magnitude of the current flowing through the semiconductor particles is related to the size information of the semiconductor particles. Therefore, by adjusting the size of the semiconductor particles, it is possible to adjust the magnitude of the current flowing through the semiconductor particles, and then adjust the refrigeration capacity of the semiconductor particles to meet the cooling requirement of the electrical appliance.

[0046] Combined with Figures 1 to 3 the semiconductor refrigeration component shown, the present disclosure provides an optimization method for the semiconductor refrigeration component. As Figure 4 shown, it includes:

[0047] S401, obtaining the actual working temperature and the theoretical working temperature of the semiconductor refrigeration component.

[0048] S402, adjusting the parameter information of the semiconductor particles according to the actual working temperature and the theoretical working temperature.

[0049] S403, optimizing the design of the semiconductor refrigeration component according to the adjusted parameter information of the semiconductor particles.

[0050] The optimization method for the semiconductor refrigeration component provided by the embodiments of the present disclosure adjusts the parameter information of the semiconductor particles to adjust the magnitude of the current flowing through the semiconductor particles, and then realizes the adjustment of the refrigeration capacity and heating capacity of the semiconductor refrigeration component to meet the requirements of different electrical appliances. In this way, differential design of the semiconductor refrigeration component is realized according to the cooling requirements of different electrical appliances to meet the cooling requirements of different electrical appliances and improve the practicability of the semiconductor refrigeration component.

[0051] Specifically, when the actual working temperature and the theoretical working temperature of the semiconductor refrigeration component are the same or close, it means that the requirements of the electrical appliance are met.

[0052] Combination Figure 5 As shown, another optimization method for a semiconductor refrigeration component provided by an embodiment of the present disclosure includes:

[0053] S501, obtain the actual working temperature and the theoretical working temperature of the semiconductor refrigeration component.

[0054] S502, calculate the difference ΔT between the actual working temperature and the theoretical working temperature.

[0055] S503, determine the optimized parameter value of the semiconductor particles according to the difference ΔT.

[0056] S504, adjust the parameter information of the semiconductor particles according to the optimized parameter value.

[0057] S505, perform an optimized design on the semiconductor refrigeration component according to the adjusted parameter information of the semiconductor particles.

[0058] In this embodiment, by the difference between the actual working temperature and the theoretical working temperature, that is, to determine the difference between the current refrigeration temperature of the semiconductor particles and the target refrigeration temperature of the electrical appliance, and to determine the difference between the current heating temperature of the semiconductor particles and the target heating temperature of the electrical appliance, so as to determine whether the current working temperature of the semiconductor particles can meet the requirements of the electrical appliance. If not, it is necessary to adjust the size parameter of the semiconductor particles according to the difference ΔT, and then adjust the current flowing through the semiconductor particles, so as to adjust the refrigeration capacity and heating capacity of the semiconductor particles, so as to change the refrigeration temperature and heating temperature of the semiconductor particles to meet the working temperature required by the electrical appliance and improve the practicability of the semiconductor refrigeration component.

[0059] Specifically, when the current refrigeration temperature of the semiconductor particles is the same as or close to the target refrigeration temperature of the electrical appliance, and the current heating temperature of the semiconductor particles is the same as or close to the target heating temperature of the electrical appliance, that is, the actual working temperature and the theoretical working temperature of the semiconductor refrigeration component are the same as or close to each other.

[0060] Exemplarily, when the difference between the current refrigeration temperature of the semiconductor particles and the target refrigeration temperature of the electrical appliance tends to zero, and the difference between the current heating temperature of the semiconductor particles and the target heating temperature of the electrical appliance tends to zero, that is, the actual working temperature and the theoretical working temperature of the semiconductor refrigeration component are the same as or close to each other.

[0061] Combination Figure 6 As shown, another optimization method for a semiconductor refrigeration component provided by an embodiment of the present disclosure includes:

[0062] S601, obtain the actual working temperature and the theoretical working temperature of the semiconductor refrigeration component.

[0063] S602, calculate the difference ΔT between the actual working temperature and the theoretical working temperature.

[0064] S603. Determine the difference threshold corresponding to the difference ΔT according to the difference ΔT.

[0065] S604. When the difference ΔT is greater than or equal to the difference threshold, calculate the optimized parameter value of the semiconductor particles according to a preset formula; where the preset formula is: B = K×ΔT / 2; where B is the optimized parameter value of the semiconductor particles and K is a preset coefficient.

[0066] S605. Adjust the parameter information of the semiconductor particles according to the optimized parameter value.

[0067] S606. Optimize the design of the semiconductor refrigeration component according to the adjusted parameter information of the semiconductor particles.

[0068] In this embodiment, when the refrigeration temperature and the heating temperature of the semiconductor particles do not meet the operating temperature required by the electrical appliance, calculate the optimized parameter value of the semiconductor particles, so as to adjust the size parameter of the semiconductor particles according to the optimized parameter value, and then make the refrigeration temperature and the heating temperature of the semiconductor particles meet the operating temperature required by the electrical appliance, improving the practicability of the semiconductor refrigeration component.

[0069] Combined with Figure 7 As shown, another optimization method for a semiconductor refrigeration component provided by an embodiment of the present disclosure includes:

[0070] S701. Obtain the actual operating temperature and the theoretical operating temperature of the semiconductor refrigeration component.

[0071] S702. Calculate the difference ΔT between the actual operating temperature and the theoretical operating temperature.

[0072] S703. Determine the difference threshold corresponding to the difference ΔT according to the difference ΔT.

[0073] S704. When the difference ΔT is greater than or equal to the difference threshold and the difference is the cold-end difference ΔT1, K = 0.1, B1 = 0.1×ΔT1 / 2; B1 is the first optimized parameter value of the semiconductor particles.

[0074] S705. When the difference ΔT is greater than or equal to the difference threshold and the difference is the hot-end difference ΔT2, K = 0.05, B2 = 0.05×ΔT2 / 2; B2 is the second optimized parameter value of the semiconductor particles.

[0075] S706. Adjust the parameter information of the semiconductor particles according to the optimized parameter value.

[0076] S707. Optimize the design of the semiconductor refrigeration component according to the adjusted parameter information of the semiconductor particles.

[0077] In this embodiment, when the cold-end difference ΔT1 of the semiconductor particles is greater than the difference threshold, it indicates that the refrigeration temperature of the semiconductor particles does not meet the operating temperature required by the electrical appliance. Therefore, it is necessary to calculate the optimized parameter values of the semiconductor particles, so as to adjust the size parameters of the semiconductor particles according to the optimized parameter values, and then make the refrigeration temperature and heating temperature of the semiconductor particles meet the operating temperature required by the electrical appliance, improving the practicability of the semiconductor refrigeration component.

[0078] Furthermore, the K values corresponding to the cold-end temperature difference and the hot-end temperature difference are set differently because after adjusting the size parameters of the semiconductor particles, the temperature change at the hot end is greater than that at the cold end. Therefore, the K value corresponding to the hot-end temperature difference is designed to be greater than the K value corresponding to the cold-end temperature difference, so as to reduce the problem that the temperature change at the hot end is large after adjusting the size parameters of the semiconductor particles, resulting in the need for reverse adjustment. To reduce the number of adjustments and the complexity of optimizing the semiconductor refrigeration component.

[0079] Specifically, if the hot-end temperature is high, that is, the hot-end temperature difference ΔT2 is greater than the difference threshold, it is because the refrigeration capacity of the semiconductor refrigeration component is too large and does not match the heat dissipation capacity. Then, the size parameters of the particles should be increased to reduce its refrigeration capacity, thereby reducing its heat dissipation to match the heat dissipation system.

[0080] If the hot-end temperature is within the expected range and the cold-end temperature is too high, it is due to too small refrigeration capacity. In subsequent designs, the size parameters of the particles should be reduced to increase the refrigeration capacity of the device so that it can meet the refrigeration capacity required by the electrical appliance.

[0081] Combined with Figure 8 As shown, another optimization method for the semiconductor refrigeration component provided by the embodiment of the present disclosure, the difference threshold includes a first threshold and a second threshold, and the optimization method includes:

[0082] S801, obtain the actual operating temperature and the theoretical operating temperature of the semiconductor refrigeration component.

[0083] S802, calculate the difference ΔT between the actual operating temperature and the theoretical operating temperature.

[0084] S803, when the difference is the cold-end difference ΔT1, determine that the difference threshold corresponding to the cold-end difference ΔT1 is the first threshold.

[0085] S804, when the difference is the hot-end difference ΔT2, determine that the difference threshold corresponding to the hot-end difference ΔT2 is the second threshold; where the first threshold is less than the second threshold.

[0086] S805. When the difference ΔT is greater than or equal to the difference threshold, calculate the optimized parameter value of the semiconductor particles according to a preset formula; where the preset formula is: B = K×ΔT / 2; where B is the optimized parameter value of the semiconductor particles and K is a preset coefficient.

[0087] S806. Adjust the parameter information of the semiconductor particles according to the optimized parameter value.

[0088] S807. Optimize the design of the semiconductor refrigeration element according to the adjusted parameter information of the semiconductor particles.

[0089] In this embodiment, by setting different difference thresholds corresponding to the cold-end difference and the hot-end difference, to adapt to the situation that after adjusting the size parameter of the semiconductor particles, the change range of the hot-end temperature of the semiconductor refrigeration element is greater than that of the cold-end temperature. To reduce the problem that after adjusting the size parameter of the semiconductor particles, the temperature change at the hot end is large, resulting in the need for reverse adjustment. To reduce the number of adjustments and the complexity of optimizing the semiconductor refrigeration element.

[0090] Optionally, the value range of the first threshold is 0.5°C to 1.5°C. The specific values of the first threshold include: 0.5°C, 1°C, and 1.5°C.

[0091] Optionally, the value range of the first threshold is 1.5°C to 2.5°C. The specific values of the first threshold include: 1.5°C, 2°C, and 2.5°C.

[0094] S902. Calculate the difference ΔT between the actual operating temperature and the theoretical operating temperature.

[0095] S903. Determine the optimized parameter value of the semiconductor particles according to the difference ΔT.

[0096] S904. When the actual operating temperature is the cold-end actual operating temperature, calculate the difference between the cross-sectional ratio and the optimized parameter value as the adjusted cross-sectional ratio of the semiconductor particles;

[0097] S905. When the actual operating temperature is the hot-end actual operating temperature, calculate the sum of the cross-sectional ratio and the optimized parameter value as the adjusted cross-sectional ratio of the semiconductor particles; where the cross-sectional ratio is the ratio between the height of the semiconductor particles and the cross-sectional area of the semiconductor particles along the current direction.

[0098] S906. Optimize the design of the semiconductor refrigeration component according to the adjusted parameter information of the semiconductor particles.

[0099] In this embodiment, by adjusting the cross-sectional ratio of the semiconductor particles, the size information of the semiconductor particles, that is, the parameter information of the semiconductor particles, is adjusted to adjust the magnitude of the current flowing through the semiconductor particles, thereby adjusting the refrigerating capacity and heating capacity of the semiconductor refrigeration component to meet the requirements of different electrical appliances.

[0100] Specifically, the cross-sectional ratio of the semiconductor particles can be reduced by reducing the length of the semiconductor particles or increasing the cross-sectional area along the current direction. The cross-sectional ratio of the semiconductor particles can be increased by increasing the length of the semiconductor particles or reducing the cross-sectional area along the current direction.

[0101] Combined with Figure 10 As shown, another optimization method for the semiconductor refrigeration component provided by the embodiment of the present disclosure includes:

[0102] S1001. Obtain the actual working temperature and theoretical working temperature of the semiconductor refrigeration component.

[0108] In this embodiment, by calculating the absolute value of the difference between the actual working temperature and the theoretical working temperature, the difference between the refrigerating temperature and heating temperature of the current semiconductor refrigeration component and the target working temperature of the electrical appliance is determined, thereby determining whether the current semiconductor refrigeration component meets the requirements of the electrical appliance and improving the accuracy of adjusting the semiconductor refrigeration component.

[0109] Combined with Figure 11As shown, an embodiment of the present disclosure provides another optimization method for a semiconductor refrigeration component.

[0113] S1104, calculate the difference between the adjusted height value and the target thickness value as the height of the optimized plate body assembly.

[0114] In this embodiment, by determining the height of the optimized plate body assembly according to the adjusted height value and the target thickness value of the semiconductor refrigeration component, the sum of the height of the optimized plate body assembly and the adjusted height value of the semiconductor particles can meet the overall thickness of the semiconductor refrigeration component to reach the thickness of the thermal insulation layer, which is convenient for installation. Moreover, it can enhance the assembly strength of the semiconductor refrigeration component and reduce the damage of the semiconductor refrigeration component.

[0115] Exemplarily, the target thickness value is the thickness of the thermal insulation layer of the electrical appliance.

[0116] Combined with Figure 12 As shown, an embodiment of the present disclosure provides another optimization method for a semiconductor refrigeration component. The optimization method includes:
